I want to make an Animal (Husky) follower but I don't know how, I know its different to NPC followers but other than that I have no idea.

If anybody knows how I would very much appreciate it, thanks.

It's not really that much different. I would start with the regular follower tutorials so you learn the basics. Once you understand how a regular follower works, you'll at least know what you're doing so when you encounter differences with the animal you'll know what questions you need to ask. Also take a look at the regulard dog followers like Meeko and/or Vigalance. One of the main difference between the animal followers and regular NPC followers are the Alias that's used, but it's in the same quest so easy to find when you know regular followers. I

don't have Dawnguard, but I don't imagine it would be much different than a regualar dog. The Husky mesh is one of the things I'm most looking forward to in Dawnguard.

I know how regular followers work, what do I need to change for animal followers.

Tanis, it seems like just changing the animal type from human?? to dog should do. I too am trying to have an animal follower.
I was trying to write a script to fetch. Not a stick, a dead hawk.
